I recently started talking to a friend after a long gap which came due to a misunderstanding. What is the best way to make her open up to me again?

I recently told my best friend that I have feelings for her. I knew she did not feel the same way about me, but I just did not want to hide my feelings from her. She has stopped talking to me. I have tried a lot but she refuses to reply to me. I just need my best friend back. What should I do?

Please tell me if those questions are the same.
